Hi Pankaj,

You need to debug your flash writing.  This is board and processor 
specific, and I have basically no knowledge of either so I can only give 
general guidance.

Try writing to flash using command line commands, erasing flash, etc. 
Once that works, figure out where in flash your env is being saved... 
see if anything is being saved there when you do the "saveenv", why it 
isn't being saved or why it is being corrupted.

Also, please honor u-boot email list etiquette:
